如何更正 "The injection target must not be declared static." 警告

Question

我收到警告

"The IssuePermitProcessManager.ecmManagerLocal injection target must not be declared static."

在我的 WebSphere 9 服务器控制台上。我相信导致问题的代码是：

@Stateless
@TransactionManagement(TransactionManagementType.BEAN)
public class IssuePermitProcessManager implements IssuePermitProcessManagerRemote, IssuePermitProcessManagerLocal {

    @Resource
    private UserTransaction userTransaction;

    @EJB
    protected static EcmManagerLocal ecmManagerLocal = null;
    protected final static String EcmManagerLocal_JNDI = "ejblocal:gov.mo.dnr.ecwis.sessions.ecm.EcmManagerLocal";

我不清楚注入目标是什么。我只是从 protected static EcmManagerLocal ecmManagerLocal = null; 声明中删除 static 吗？

Answer 1

是的，ecmManagerLocal 是一个声明为静态的注入目标（用 @EJB 注释以注入 ejb）。替换代码行，

    @EJB
    protected static EcmManagerLocal ecmManagerLocal = null;

和

    @EJB
    protected EcmManagerLocal ecmManagerLocal;
